Hi MeatWar

@MeatWar : Thanks for replying, sorry I missed it at first.

I used the BIOS uploaded by Fernando posted on page 1 (after my I couldn't see my drive with my own BIOS mod).

Yeah, I used the Bios Flashback and am fairly sure that I can confirm that the flash was successful. My test: I flashed to an old BIOS, then to the Fernando BIOS and checked that the version number changed in the BIOS settings.

My NVME drive is a SANDISK X600 M.2 2280 256GB (P/N SD9SN8W-256G-1006)

Thanks

I've shared a Modded Sabertooth Z87 BIOS in secrtion "Offers: Already modded special BIOSes"
Hope this can help.
[OFFER] ASUS Sabertooth Z87 2302 with NVME support + Update (Microcode V28 / GOP driver / Intel Gigabit for I217)


I've seen some fellas talking about the problems of their modded Sabertooth Z87 BIOS. However, I've never encounter any problem with my modded BIOS.
I modded my first Sabertooth Z87 BIOS with NVME support back in 2018, it has been 2 years to now that I never encounter any problem. So I just took my modded BIOS out again and update it with latest microcode and drivers, share it with everyone, hope it can help some people who has problem modding it.

This helped out alot. I had the exact same problem. i was using a 32gb flashdrive, it kepted blinking from a min to 1.5 min, then just went a solid blue, ill post a link to where if anyone needs the Bios renamer for Bios flash back. also Key note i had to go buy another flashdrive usb its 8 GB and it worked the first time thankfully the USB exactly was called swing 8GB URIREX2.0. apparently you can only do it with im guessing 2GB to 8GB. The website for the bios renamer is https://www.softpedia.com/get/System/Sys...BRenamerl.shtml
